U.S. Secretary of State Marco Rubio arrived in Sweden for a high-stakes meeting with NATO foreign ministers as European allies increasingly question the reliability of the United States under President Donald Trump and brace for potential changes to America’s military role across the continent.
Rubio’s visit comes during one of the most uncertain periods for the transatlantic alliance in years, with NATO governments facing growing anxiety over the Trump administration’s shifting military policies, escalating tensions surrounding the Iran conflict and fading hopes for a diplomatic breakthrough in the Russia-Ukraine war.
The meeting in Helsingborg, Sweden, serves as a key preparatory session ahead of a NATO leaders’ summit scheduled to take place in Turkey in July. However, instead of focusing solely on long-term alliance strategy, much of the attention has centered on confusion surrounding Washington’s commitment to European defense and concerns that the United States may gradually scale back its military presence on the continent.
At the same time diplomats gathered in Sweden, senior Pentagon officials were expected to brief NATO representatives in Brussels on future U.S. force commitments in Europe, including possible troop reductions and changes to the alliance’s defense posture.
European officials have struggled in recent months to interpret contradictory signals coming from Washington. Trump has repeatedly criticized NATO allies for what he describes as insufficient support for U.S. military operations and inadequate defense spending, while also pressuring European governments to take greater responsibility for their own security.
Rubio has increasingly become the administration’s primary diplomatic figure tasked with reassuring nervous allies and softening the tone of Trump’s confrontational rhetoric. Throughout the year, he has been deployed to major international meetings where U.S. relationships with partners appeared strained.
Earlier this year, Rubio attended the Munich Security Conference amid rising European concern over Trump’s foreign policy direction. More recently, he traveled to Italy to meet government officials and Pope Leo XIV after Trump publicly criticized the American-born pontiff over comments related to immigration, crime and the Iran war.
Despite Rubio’s efforts to present a steadier diplomatic message, uncertainty surrounding U.S. military policy has continued to unsettle NATO capitals.
Before departing for Sweden, Rubio declined to clarify whether additional American troop reductions in Europe were being considered, particularly regarding U.S. commitments under NATO’s Force Model, a collective defense framework designed to respond rapidly during major security crises.
The confusion deepened after the Trump administration previously moved to halt deployments involving thousands of American troops headed for Poland and Germany, only for Trump to unexpectedly announce on social media that the United States would instead send an additional 5,000 troops to Poland.
The abrupt shift left NATO officials and defense analysts scrambling to determine whether the suspended deployment had been reinstated, whether new troops would be added on top of existing rotations, or whether troop reductions might still occur elsewhere in Europe.
Neither the Pentagon nor the White House immediately provided detailed clarification about the president’s announcement, fueling additional uncertainty among allies already concerned about the long-term direction of U.S. defense policy.
Rubio acknowledged frustrations within the administration regarding NATO’s response to the Iran conflict, signaling that Trump remains dissatisfied with several alliance members.
“I don’t think anyone is shocked to know that the United States, and the president in particular, is very disappointed at NATO right now,” Rubio told reporters before boarding his flight to Sweden.
Although Rubio reaffirmed his support for NATO and described the alliance as strategically important, he sharply criticized some member states for refusing to fully support U.S. operations linked to the Iran conflict.
He specifically pointed to Spain’s reluctance to grant expanded access to American military bases and criticized several NATO countries for failing to join efforts aimed at securing the Strait of Hormuz, the vital energy shipping route heavily affected by the ongoing conflict with Iran.
Rubio argued that the strategic value of NATO for the United States depends partly on allies allowing Washington to use military infrastructure across Europe to project power globally.
“I know why NATO is good for Europe, but why is NATO good for America?” Rubio said during remarks to reporters. He then questioned why countries benefiting from American protection would restrict U.S. military access during a major international crisis.
The secretary of state also emphasized that while many NATO members publicly oppose Iran obtaining nuclear weapons, few were willing to provide meaningful support after Trump pledged to take military action aimed at preventing Tehran from advancing its nuclear program.
Rubio stressed that the administration was not demanding troop deployments or combat aircraft from allies, but he suggested the White House was frustrated by what it views as limited political and logistical backing from Europe.
“He’s not asking them to commit troops. He’s not asking them to send their fighter jets in,” Rubio said of Trump. “But they refuse to do anything.”
The growing divide between Washington and several European capitals has intensified debates inside NATO about the future structure of the alliance and the extent to which Europe must prepare to operate more independently from the United States.
NATO Secretary-General Mark Rutte attempted to reassure allies earlier this week, stating that member governments had long been aware that the Trump administration intended to reduce some U.S. troop levels in Europe over time.
Rutte said the administration expects European nations and Canada to assume greater responsibility for NATO’s conventional defense capabilities, particularly in Europe itself.
At the same time, he stressed that the United States would remain engaged in NATO even if portions of its military resources are redirected toward other global priorities, including the Indo-Pacific region.
U.S. Gen. Alexus Grynkewich also sought to calm concerns by insisting European security would not be compromised by troop adjustments. However, he warned allies to expect additional reductions in the coming years as Washington reevaluates its global military posture.
The Trump administration has repeatedly argued that Europe must increasingly manage its own security challenges, including long-term support for Ukraine, as the United States focuses on other strategic priorities.
Those comments have fueled fears among some European leaders that Washington’s commitment to NATO may become more conditional and less predictable under Trump’s leadership, particularly during periods of international crisis.
Beyond military issues, tensions between the United States and European allies have also been aggravated by Trump’s repeated criticism of NATO members over defense spending and trade, as well as his controversial remarks about Greenland, the autonomous Danish territory that remains strategically important in the Arctic.
For many European diplomats attending the Sweden meeting, Rubio’s mission was not only about discussing defense strategy but also about preventing growing mistrust within the alliance from deepening further at a time when NATO faces mounting geopolitical challenges on multiple fronts.
